Title: Heat exchanger and its operation method
Inventor: KOJIMA EIICHI
IPC: E01F9/619
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent hydrophilic nature of a hydrophilic surface layer formed on the surface of a fin of a heat exchanger from being lowered with the lapse of time. SOLUTION: A heat exchanger is adapted such that many fins 2... are mounted oppositely on a pipe 1 through the inside of which a heat medium flows, and that each fin 2 comprises an aluminum flat plate on the surface of which a surface layer 3 is formed. The surface layer 3 uses silicone resin having an Si-O bond in the form of a matrix in which TiO2 particles are dispsersed as optical semiconductor particles. The surface layer 3 exhibits hydrophilic nature by irradiating it with light having a wavelength capable of exciting the TiO2 (ultraviolet rays) from a light source 4.

Title: Thin film transistor array and its production
Inventor: OKABE KAZUYA
IPC: G02F1/1362
Filed: 1987-04-23
Abstract: PURPOSE:To enable formation of one feed terminal to a larger size and taking of a wider spacing between terminals by forming an auxiliary bus for conducting a source bus or gate bus from which a short-circuited point is disconnected by laser trimming onto said source bus or gate bus so that power feeding is necessitated to be executed from the terminal on one side. CONSTITUTION:The source bus or gate bus on both sides of the short-circuited point is subjected to the laser trimming to disconnect the short-circuited point from the source bus or gate bus and the auxiliary bus to conduct the cut source bus or gate bus is formed. The feed terminal for the source bus or bate bus is, therefore required to be provided to only one side and consequently, the number of the terminals is reduced by half and the larger sized terminal can be formed. In addition, the spacing between the terminals can be widened and therefore, the short-circuit between the terminals decreased. Power feed to a thin film transistor TFT existing between the short-circuited points can be made even if there are >=2 short-circuited points in one source bus or gate bus. The disabled TFTs are thereby decreased and the yield is improved.

Title: Method for growing compound semiconductor single crystal
Inventor: YOSHITAKE SHINJI
IPC: H01L21/18
Filed: 1986-05-02
Abstract: PURPOSE:To inhibit the shift of the position of a solid-liquid interface and to secure the stable growth of crystal by descending the temp. of a melt in coincidence with the growth of crystal in a horizontal Bridgman's method. CONSTITUTION:In the growth of compd. semiconductor single crystal by a horizontal Bridgman's method, the concn. of impurities incorporated in a melt is made high as the growth of crystal is progressed and m.p. of the melt is lowered and the position of the interface of crystalline growth is shifted to a low-temp. side. As a result, the growth of crystal is made unstable. Therefore the temp. of the melt is continuously or intermittently lowered in coincidence with the growth of crystal and the fluctuation of the position of a solid-liquid interface is made small and thereby the growth of crystal is made stable. As a result, single crystal such as GaAs which has little crystalline flaw and good quality can be obtained.
